A hot-side slab leak
A warm patch on the floor, a water heater that runs constantly, or hot water that takes forever to arrive. We isolate the hot side from the cold to confirm which line is leaking before we talk about repair.

Slab Leaks in Cary
Slab leak problems we see in Cary homes
Most slab leak calls fit one of these six. Tell us which sounds like yours and we will tell you how we would find it.
A water bill that jumped
Usage up, household unchanged. We check whether the water is being lost inside the house, under the slab, or somewhere else, and we do it before suggesting any repair.
A warm or damp spot in the floor
Tile that feels warm, grout that stays wet, or carpet that smells musty near one wall. We use listening equipment and pressure testing to pinpoint the spot so the opening in your floor is as small as it can be.
Cracked slab or leaking pipe?
A crack in the floor and a leak under it are not the same problem, and clay soil movement can cause either one. We test the lines to tell you whether the plumbing is leaking or the slab is simply cracked.
A second opinion on a repipe quote
If you were told the whole house needs a repipe, we can check the leak, test the system, and tell you whether a spot repair or reroute would do the job. If a repipe is the right call, we will say so.
Leak detection before you buy
Buying a slab home in Cary from the 1980s or 1990s? We can test the supply lines and check for signs of an active leak, and for polybutylene piping, before you close.
Clear Answers
How we handle a slab leak
- 1
Tell us what you noticed
The bill, the warm spot, the sound, or the damp floor. We ask when it started and whether hot, cold, or both seem affected. You get an arrival window and the price before work starts.
- 2
Detection first
We listen along the floor and lines, pressure-test the system, and isolate hot from cold. We locate the leak and the line it is on before we propose anything, so nobody opens the floor on a hunch.
- 3
Options with a price
Spot repair through the slab, a reroute overhead or through the walls, or a repipe if the system is failing. You get each option with its price, and nothing starts until you approve it.
Slab Leaks in Cary Homes
Why Cary slab homes get leaks
Most of Cary was built between the 1980s and the 2000s, and Cary homes are a mix of slab-on-grade and crawlspace construction. On a slab, a pinhole leak in a copper line can hide under the floor and show up only as a high water bill or a warm spot on the tile. In a crawlspace we can often see the leak. On a slab we have to find it, which is why detection comes first here.
Cary is also right in the 1978 to 1995 window when polybutylene supply piping was used in the Triangle. If your home is in an established neighborhood such as Kildaire Farms, MacGregor Downs, Scottish Hills, or Greenwood Forest, it is worth knowing what is actually in your walls. Triangle clay soil swells and shrinks with the seasons and can move a line under the slab. When one leak is found in a system like that, we look at the condition of the rest before recommending a repair, a reroute, or a repipe. For other leaks, see leak repair.
Our shop is at 3460 Apex Pkwy, on the Apex side of the town line, so most Cary addresses are a short drive. We work Monday through Saturday, 7:00 to 18:00. If you suspect a slab leak, shut off the main water valve if you can reach it safely and call. For everything else in the house, see our Cary plumber page.

Helpful Details
Slab leak questions in Cary
How do I know if I have a slab leak in my Cary home?
The common signs are a water bill that jumps with no change in usage, the sound of running water when everything is off, a warm spot on the floor, or damp flooring. Many Cary homes are on slabs, so the leak can be hidden. Call us and we will locate it before talking about repair.
Do you offer slab leak detection in Cary without repair?
Yes. Detection is the first step on every slab leak job. We use listening equipment, pressure testing, and hot-versus-cold isolation to find where the water is going. You get the findings and the options, and you decide what happens next.
How much does slab leak repair cost in Cary?
It depends on where the leak is, how many lines are involved, what the flooring is, and whether you choose a spot repair, a reroute, or a repipe. We give you the price before we start, and nothing happens until you approve it.
Is it a slab leak or a burst pipe?
A burst pipe usually announces itself with water where it should not be. A slab leak is quieter. It is slower and hidden, and it shows up as a bill, a warm spot, or a smell. Either way, shut off the main if you can and call (919) 679-1275, and we will tell you what we are looking at.
My Cary home was built in the early 1990s. Could the pipes be polybutylene?
Possibly. Homes built roughly between 1978 and 1995 in the Triangle may have it, though many have since been repiped. We can check what you have and tell you honestly whether a repipe is needed or whether a repair is enough.
Can you give a second opinion on a repipe quote?
Yes. We will locate the leak, test the system, and tell you what we find. Sometimes a repair or reroute solves it. Sometimes a repipe is the right answer, and we will say so.
